The Online PHP Editor uses PHP version 8.3.
There you will see two sections.

The output can be an error or the successful outcome of your php code.
There is a sample php code provided by default.
Just click on the Run button below and see the outcome on the right.
Or, you can enter your own php code and then click on the Run button to see the outcome on the right.
While entering the php code, just make sure that you do not use the disabled functions, file handling functions, or the database connections functions as this is a very basic type of online php editor.
Also, check the length of your php code according to the restrictions.
